To all whom it may concern:

Be it known that I, CARL A. SCHELL, a

citizen of the United States,- residing in Cleveland, Ohio, have invented certain Improvements in Flexible Disks for Couplings,

" One object of my invention is toconstruct a flexible disk for use in connection with flexible couplings so that the disk will have the required amount of strength and the desired flexibility.

A, further object of the invention. is to make a disk of plies of fabric united by vulcanizable material and one or more rings of cords at the "sides of the disk united to the pads being at I. to provide {a reinforcing .pad at the bolt holes, in combination with the disk and cords so that washers can be shaped to correspond to the shape of the pads inorder to provide means for firmly holding the disk to the spiders. I

These objects I attain in the following'manner reference being bad to the accompanying drawings, in which:

Fig. 1 is a face view of my improved disk; y

Fig.2 is an edge view of the disk;

Fig. 3 is a sectional view on theline 3-3,

Fig. 4 isja sectional view on the line 4-4,.

' Fig. 1; and

I of cords 6 and 7. The cords 7 extend near Fig. 5 is a sectional view illustrating the means for securing the isk to one of the rms of a spider.

the passage ofthesecuring bolts, which -fas-' ten the disk to the spiders, one of which is shown at 5, Fig. 5. At each side of the body portion 1 of the disk are two series on the inner side of the bolt holes, as

shown. These cords are continuous.

Surrounding each bolt are pads 8 of rubher, which enclose the'cords at this point.

The cords are straight between the adjoining pads so as to take the torsional strains to which the disk is subjected. They are also united to the body of the disk by webs 9 of rubber, as shown in Fig. 4, at points between the pads. In order to prevent the plies of the body of the disk from separating at the central opening, the edges are enclosed by a ring 10 of rubber having flanges 11, which extend over the edge of the opening.

, When these parts are assembled, as shown, theyare vulcanized under pressure producing an integral disk.

While a cord may be of four strands, as shown, it will be understoodthata single cord may be used, or a number of small cords, without departing from the essential features of the inventio I claim:

1. A flexible disk for flexible couplings consisting of a body portion of fabric and rubber vulcanized; rings of cords at each side of the disk; pads, said disk having a series ofbolt holes; and pads at the bolt holes enclosing thecords. I

2. A disk for flexible couplings consisting of a series of lies of fabric and rubber;

two rings of cor s at each side of the disk, the cords being spaced apart; bolt holes in the disk between the two series of cords; and pads at the bolt holes extending 'over both cord rin j 3. A di sk for flexible couplings consisting'of plies of fabric and rubber; a series of cord rings at each side of the disk bolt holes in the disk between the rings of cords;

and pads at the bolt holes, the cords be tween the pads being straight so as to take thetorsional strains to which the disk is sub ected. 1
